(ii)its potential relevance to the exercise of any function by the TRA under the Act or these Regulations;
(b)a “statement of reasons” means a statement setting out the reasons of a person supplying information to the TRA as to why the TRA should treat that information as confidential and why summarisation of that information in accordance with this regulation is not possible.
